Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a belt attachment structure for a liquid container, and particularly to a belt attachment structure for a portable thermos bottle.

[Conventional technology]

The conventional structure for attaching a belt to a portable thermos flask is generally such that the end of the belt is passed through a mounting shaft provided on the container side, folded back, and the folded end is fixed to an adjustment tool provided midway through the belt. In addition, as another structure, there is a structure in which a ring is provided at the end of the belt and this ring is detachably attached to a mounting shaft on the container side.

[Problem that the invention attempts to solve]

According to the former structure described above, it is impossible to freely attach and detach the belt, or even if it is possible, there is a problem in that it takes time to attach and detach the belt. In addition, according to the latter structure, attachment and detachment operations are much easier than in the former case, but the structure is complicated because it is necessary to provide a claw on the ring to prevent it from coming off, and to impart spring elasticity to the claw. Therefore, there is a problem of high cost.

Therefore, the object of this invention is to provide a belt attachment structure that is easy to attach and detach and can be manufactured at low cost.

[Means for solving problems]

In order to solve the above problems, this invention fixes a pair of upper and lower mounts 2 parallel to the transverse direction on the outer periphery of the container body 1, and supports each mount 2 on the end surface of the container end side. A shaft 3 is provided, and hooks 5 that engage with the support shaft 3 at a constant engagement depth ₁ are attached to both ends of a belt 4 formed separately from the container body 1. Distance from trunk 1 ₂
and the maximum distance ₃ between the support shaft 3 and the container body 1 in a state where a portion of the hook 5 is in contact with a portion of the mounting base 2, respectively, is set to a distance smaller than the engagement depth ₁ , and The spacing ₄ between the support shaft 3 and the end face of the mounting base 2 is set to be larger than the engagement depth ₁ described above.

[Operation] With the hook 5 engaged with the support shaft 3, the hook 5 rotates around the support shaft 3. The hook 5 rotates from a position along the container body 1 (see FIG. 2) to a range where it hits the mounting base 2 (see FIG. 4). At this time, only when the hook 5 is along the container body 1, the distance ₄ between the support shaft 3 and the mounting base 2 becomes larger than the engagement depth ₁ of the hook 5, and the hook 5 comes off. At other positions, compared to the engagement depth ₁ of the hook 5, the support shaft 3 and the container body 1
The interval ₂ or ₃ between is smaller, and the hook 5
cannot be removed.

Therefore, the hook 5 is attached and detached while being parallel to the container body 1.

〔Example〕

The embodiment shown in the drawings is a heat-retaining pot having a cylindrical container body 1 made of a double vacuum bottle made of stainless steel. This heat-retaining pot is located in the container body 1.
A bottom body 6 is fixed to the lower end of the container, and a cap 7 which also serves as a lid is fitted to the upper end of the container body 1. Two parallel handle bars 8 are provided along the length of the container body 1. The container is carried with the container body 1 lying on its side.

A pair of mounts 2 for attaching the handle bar 8 are provided on the outer periphery of the container body 1, parallel to the transverse direction thereof, above and below.

The upper mounting base 2 is fixed by screws 11 to a handle base 10 which is stud-welded to the outer peripheral surface of the outer container 9 of the container body 1, as shown in FIGS. 5 and 6.

The lower mounting base 2 has a mounting bracket 12 (see Figure 8).
is fixed to the outer peripheral surface of the bottom body 6 by projection welding, and is attached to the mounting bracket 12 with screws.

A pair of hinges 13 are provided in the center of each mounting base 2 mentioned above.
A handle bar 8 is provided integrally with each hinge 13. When carrying, as shown in Figure 9, each hinge 1
3 and align the two handle bars 8. When the container is carried by the hanging belt 4 or stored, the hinges 13 are folded down to increase the distance between the handle bars 8 and to bring them closer to the container body 1, as shown in FIG.

In order to support the container by the hanging belt 4, the support shafts 3 that engage the hooks 5 are attached to the upper end surface of the upper mount 2 and the lower end surface of the lower mount 2, respectively. These support shafts 3, as shown in FIG.
It is made of a metal rod bent into a U-shape, and has engagement grooves 14 formed in the circumferential direction at both ends thereof. Both ends of the support shaft 3 are inserted from the end face of the mounting base 2,
The E-shaped clip 15 is inserted into the engaging groove 14 inside the E-shaped clip 15.
Attach by engaging with (see Figure 6).
On the other hand, as shown in FIG. 1, the hook 5 of the hanging belt 4 is formed to have a width slightly wider than that of the belt 4, and consists of an insertion part 5a of the belt 4 and an engaging part 5b. An elastic piece 5 is provided with a U-shaped notch in a part of 5b to create a click feeling when engaged.
It forms c.

As shown in FIGS. 2 to 4, the hook 5 has an engagement depth of ₁ with the support shaft 3, and the position of the support shaft 3 is determined in relation to this engagement depth of ₁ . .

That is, as shown in FIG. 3, the distance ₂ between the support shaft 3 and the container body 1 is set to be smaller than the engagement depth ₁ described above. Therefore, in a state where the hook 5 stands up with respect to the container body 1, even if the hook 5 moves in the direction in which it comes off, the tip portion thereof hits the container body 1, so that the hook 5 does not come off.

Furthermore, when the hook 5 is tilted toward the mounting base 2 from the state shown in FIG. 3 as shown in FIG. 4, part of the hook 5 hits a part of the mounting base 2 (hinge 13), The distance ₃ between the tip of the hook 5 and the container body 1 is also set to be smaller than the engagement depth ₁ . Therefore, the hook 5 will not come off in this state.

On the other hand, when the hook 5 is rotated to be parallel to the container body 1 as shown in FIG. 2, the distance ₄ between the support shaft 3 and a part of the mounting base 2 (hinge 13) is ₁ set to larger. Therefore,
In this state, when the hook 5 is moved toward the mounting base 2 as indicated by the downward arrow, the hook 5 is removed from the support shaft 3 (see the chain arrow).

As mentioned above, this container is hung on its side and carried around. Therefore, the attitude of the hook 5 in the carrying state is as shown in FIG.
It is normal to stand up almost at right angles to the
In this state, the hook 5 cannot be removed. Even if the hook 5 is tilted inward from this state (FIG. 4), the hook 5 will not come off. Also, even if the hook 5 is tilted outward, it will come off only when the hook 5 approaches the container body 1 and becomes substantially parallel to the container body 1 as shown in FIG. However, since the condition shown in FIG. 2 cannot occur in a normal hanging condition, there is no risk that the hook 5 will come off unexpectedly in a hanging condition.
The state shown in FIG. 2 cannot occur except when the user is artificially placed in such a position, that is, when the hook 5 is attached or removed.

[Effect of idea]

As described above, in this invention, the position of the support shaft 3 is set in relation to the engagement depth of the hook 5 so that it can be attached and detached only when the hook 5 is aligned parallel to the container body 1. , there is no need to provide the hook 5 with a claw to prevent it from falling out, such as a conventional ring, and the belt 4 can be detachably connected to the container body 1 with just the hook 5, and there is no risk of it coming off unexpectedly when carrying. . In addition, not only is it easy to attach and detach, but the structure of the hook is also simple.
